I have an older V1.7 purchased back in 1999. It will cost $189 to bring it up to current specs (at least I think it would be current specs).
Is this a worthwhile upgrade? I really don't care whether or not I have the latest and greatest version, but if the performance is significantly better, I'd like to do it.
Also, I've been having a few problems and I wonder if the upgrade will fix them. The problems are that I get false laser alarms from time to time - often enough to be annoying. And lately I will occasionally get a visual alarm but not an audible alarm, even though the volume is set high enough when the unit is turned on.
